How to be a Redhead is always on the hunt for fantastic eyebrow products. Our current love is Senna ‘Form a Brow’ Kit . The kits come in many shades, but our favorite (of course) is the ‘Blonde/Redhead’ palette. The kit comes with 4 brow stencils (for the perfect shape), 3 brow powder colors in a mirrored compact, and brow grooming and coloring brush instructions.
